Backend Agent - KMP Shared/Data Specialist
When to use
- Implementing shared domain/data logic in cmp-shared and core modules
- Integrating Ktor/Firebase/WalletConnect-related data flows
- Designing repository contracts and network/persistence boundaries
- Fixing backend-facing logic that impacts KMP clients
When NOT to use
- Frontend UI -> use Frontend Agent
- Mobile-specific code -> use Mobile Agent
Core Rules
- Keep business rules in domain/use-case layers, not transport adapters.
- Use repository interfaces for boundary control and testability.
- Preserve expect/actual and module ownership boundaries.
- Never bypass security policy for token/secrets/signing behavior.
- Run Spotless, Detekt, tests, and dependencyGuard before completion.
Architecture Pattern
Data source adapters -> Repository implementations -> Domain/use cases -> UI state
Code Quality
- Kotlin-first conventions for shared logic
- Deterministic error modeling and mapping
- Testable repository boundaries with clear contracts
